.T0 all wir/0m, it may concern:

Be it known that I, J nTHRo B. CRAWFORD, of Rochester, Monroe county,New York, have invented a certain new and useful Improvement inBottle-Stoppers; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, in which- Figure lis an elevation, partly insection, of a bottle with the fastener applied thereto, the stopperbeing shown as raised.` Fig. 2 is an elevation showing the stopperforced down and packed but not locked in place. Fig. 3 is a similar viewshowing the fastening locked in place. Fig. 4- is an elevation at rightangles -to Figs. l, 2,. and 3. Figs. 5 and-6 are modifications.

My improvement relates to that class of bottle-Stoppers in which thestopper is forced down by means of a lever pivoted to a neckwire andengaging with the bail.

The distinguishing feature of this invention is a bail Aprovided at itslower ends with loops in which the pivot ends of the leverrest, and soarranged that the bail is first forced down till its sides strike thepivots of the neck-wire, which serve as stops to the same, after whichthe further movement of the lever forces the pivot ends along the loopsand locks the fastening in place.

In the drawings, A shows the top of the bottle. v

B is a neck wire, having two projecting pivot ends, a a, on oppositesides. This wire may be formed in two halves, with the ends twistedtogether to form the pivots, or in any other desired way.

O is the stopper, andD the bail-wire. The bail-wire is preferably cast'into the top of the stopper, so as to be stiff withit, `as showny inFigs. l, 2, 3, 4; but, if desired, it may pass through an eye and beloose, as in the common stopper, and in some instances it is preferableto use the form of stopper shown in Fig. 6, which consists of a capstruck up from sheet metal, the rubber fitted into the cap and securedby a cross-pin, and the bail fitting in an eye made by slitting thelnetal and pressing the tongue between the slits outward. On the lowerends of the bail D are formed loops d d, as shown. These loops standnearly at right angles to the sides of the bail, but turn very slightlyupward, as shown in Fig. 3.

E is the lever, consisting of a loop of wire having intermediate eyes, gg,whichA iit around the pivots of the neck-wire, and outside of thesecrank-shaped arms 71, Iz, provided with right-angled pins i t', whichproject outward and rest in the loops d d of the bail-wire.

In applying the stopper it is first inserted in the mouth of the bottlein an inclined position, as shown in Fig. Y l. In this position thelever E is raised, and its pins stand in the outer ends of the loops dd, Fig. l. When the lever is forced down it carries the bail down withit and forces the stopper in place. The pins t' t' still remain in theouter ends of the loops till the sides of the bail strike against thepivots a a of the neck-wire, as shown in Fig. 2. In this position thebail is brought to a vertical position and the stopper is fully forcedin place and packed; but the fastening is not locked, because the pivotsstand ,in a vertical line, and if the lever is released it will ily upagain and release the packing. Then the bail is thus forced down, afurther movement is then given to the lever, which forces the pins t' ifrom the outer to the inner ends of the loops d d, as shown in Fig. 3.Then so forced out, the pins t' i stand beyond the pivots a a, andtherefore the parts are perfectly locked, and the bail cannot move up.The loops d d are of such inoline that as the pins move along them theyretain the pressure already produced on the bail, and they do not let upor yield back, as is the case of ordinary fastenings when the bailsprings past the dead-center. The holding pressure of the packing istherefore more effective, and the device is more easily opened, becausethe bail does not have to be forced down again in passing around thedead-center. A novel feature consists in first forcing the bail downtill it strikes the stops to press the packing in place, and then movingthe fulcrum-pins farther forward to lock the bail in place. If desired,the bail, instead of being in a perfectly-straight length, may haveslight bends p where they strike the pivots a a., as shown in Fig. 5.When the lever is thrown fully down, it still stands a little distancefrom the bottle, as shown in Fig. 3, by which means ICO I0 ing eyes g gresting npon the pivots, crank I ends h 7L, and pins z z', resting inthe loops of the bail, as herein shown and described.

In witness whereof I have hereunto signed my naine in the presence oftwo subscribing witnesses.
